This is best fresh with freshly squeezed lemon juice so I would make when needed. However, it will store for a few weeks in the fridge.
The recipe as written makes just about 15 tablespoons which I'm counting as 14 servings just to be safe on the nutritional info. I'd rather overestimate the macros.
If you don't have honey, maple syrup works!
If you don't have dijon mustard yellow mustard or mustard seed powder works great too.
This recipe can easily be halved it makes too much for you.
I save glass jars to reuse for homemade dressings. I'm not sure where this one came from but it's really similar to these.
